Abstract
A loose-proof screw nut comprises a screw nut body (1) and a screw thread (2). The utility model is characterized in that a penetrating translot (3) which is arranged on the upper portion of the screw nut is angled or is vertically arranged in relative to a vertical shaft line of a screw thread aperture, and the upper portion (F) is vertically pressed downward and is transformed, thereby an angle is formed between the vertical shaft line of the screw thread aperture on the upper portion and the vertical shaft line of the body screw thread aperture on the lower portion. Compared with the prior art, the utility model has the advantages of simple structure, easy processing and reliable loose proofing effect.
Description
The utility model relates to nut, particularly lock nut.
The locking problem of nut is the problem that people will solve aborning always, and lock nut has a variety ofly in the prior art, but is complex structure or complex manufacturing mostly, and the processing cost height is not very practical.
Order of the present utility model provides a kind of structure and processing technology is simple, the reliable lock nut of anti-loosening property.
Technical solution of the present utility model is made up of nut body (1) screw thread (2), it is characterized in that being provided with having and decide angle or vertical saturating horizontal poor (3) with the tapped hole longitudinal axis on the top of nut, said top (F) part is made the longitudinal axis angulation of the former body tapped hole of longitudinal axis and bottom of top tapped hole by vertically downward pressurizing and deformation.
Advantages such as the utility model has simple in structure compared with prior art, and the processing part is easy, and anti-loosing effect is reliable.
Below be to brief description of drawings:
Fig. 1 is first kind of embodiment's of the utility model a plan view
Fig. 2 is first kind of embodiment's of the utility model a plan view
Fig. 3 is second kind of embodiment's of the utility model a plan view
Fig. 4 is second kind of embodiment's of the utility model a plan view
Fig. 5 is the third embodiment's of the utility model a plan view
Fig. 6 is the third embodiment's of the utility model a plan view
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Lock nut of the present utility model as can be seen is exactly to offer on existing nut top the saturating translot (3) with the longitudinal axis of original thread hole (2) angled (as shown in Figure 5) or vertical (as Fig. 1 and shown in Figure 3) from accompanying drawing, then the downward extrusion-deformation in top of saturating translot (3), make the longitudinal axis in original thread hole and the longitudinal axis angulation of the tapped hole on saturating translot (3) top that is extruded distortion, like this when nut is screwed in the bolt, top screw thread after the bottom screw thread of its lock nut and the distortion produces inconsistent area of contact and contact stress to the screw thread in the bolt, will really play locking effect.
Second kind of embodiment of the utility model as shown in Figure 3, Figure 4, be provided with on the nut boss (4) boss (4) go up from about respectively cut a movement joint (3), locate to apply external force at (F) then and make its distortion, it is splendid to be screwed in the bolt anti-loosing effect.
Claims (1)
1 one kinds of lock nuts, formed by nut body (1) screw thread (2), it is characterized in that being provided with having and decide angle or vertical saturating horizontal poor (3) with the tapped hole longitudinal axis on the top of nut, said top (F) part is made the longitudinal axis angulation of the former body tapped hole of longitudinal axis and bottom of top tapped hole by vertically downward pressurizing and deformation.
